To all to 7mm it may concern:

Be it known that I, MARVIN C. RnYNoLDs, a citizen of the United States, and a resldent of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Barrel-Emptying Machines, of which the following is a Specification.

My invention relates to an improved barrel emptying machine particularly adaptable for removing such substances as butter, fats, waxes, etc., from barrels or casks.

I'Ieretofore it was'necessary to remove such substances by hand, a very impractical and parts shown in Fig. 4, and

Fig. 6 is a cross-sectional view on plane 66,-F1g. 8.

The machine is constructed to raise a filled barrel and support it in position with. ,ltS a'Xis horizontal, a substance removing tool being then driven through the barrel and the removed contents conveyed away from the machine.

Referring to thedrawings, the supporting .frame work for the machine comprisesside,

frames 10 and 11 connected together as necessary by cross bars and braces to afford the necessary strength, the frame-work being preferably portable by being mounted on wheels 12. At the front of the machine an elevator structure is provided for receiving the barrel, raising it, and tilting it in a horizontal position. This elevator comprises a supporting platform 13, the back wall 14 and the diagonal side braces 15. At the upper corners of the wall 14 pins 16 and 17 extend laterally for engaging in thevertical guide slots 18 and 19 formed in the vertical beams 20 and 21 forming part of the ma chine supporting frame-work. are oblong and when the elevator is down theelevator to horizontal position, the pins 1011 the shoulders 23; In order to readily The pins I they are at the bottoms of the slots 18 and. 19, and when the elevator has been raised they abut against the tops of the slots and so limlt the vertical movement, the slots at their tops havingthe lateral extensions 22 forming shoulder-s23 on which the pins rest after swing of the elevator to horizontal position.

Describing the means for raising the elevator and swinging it ,to horizontal positlon, a bail 24 is secured at its ends to the sides of the elevator platform, a cable 25 extending from the bail around the guide sheaves 26and 27 and around a drum 28. When the elevator is down and the drum rotated, the elevator is first raised until it is stopped by the engagement of the pins 16 and 17 with the upper ends of the slots. Then further pull on the cable will swing acting as pivots and entering the slot extensions 22. to rest on the shoulders 23 to support the elevator in horizontal position.

In order to lock the elevator in horizontal position independently of the cable and drum, a detent bar 29 is provided, this bar being pivoted at its outer end to the back wall of the elevator and sliding over the cross bar 30 as the elevator is raised, and when the elevator has been swung into horizontal position the detentnotch 31 receives the edge of the bar 30, the elevator being i then held in horizontal position by the detent bar and'the pins 16 and 17 which rest release the detent bar to permit return of the elevator I provide tripping mechanism. As shown, a lever 32, is pivoted at 33 and has the tripping tongue 34 extending upwardly below the end of the detent bar, a 95 link 35 connecting the free end of the lever with a treadle lever 36 pivoted to the machine frame at 37. Upon stepping against the front end of the treadle lever the lever 32 is swung upwardly to bring the tongue 100 34 against the end of the detent bar to raise the bar sufficiently to release it from the cross bar 30. A spring 38 tends to hold the Itaripping mechanism away from the detent Mounted at the top and at one side of the machine frame-work is a driving motor M, w and bearing frames 39 for the main drive shaft 40.. At the other side of the framework the counter shaft 41 is journaled in 110 suitable bearings 42, a belt 43 connecting the shaft with the main shaft. At the front end of the shaft ll the drum 28, for raising the elevator, is mounted, suitable clutch mechanism 491 being operated by a lever 4:5 to control the driving connection of the drum with the shaft. Suitable brake mechanism 16 controlled by a lever 47 is also provided for controlling the unwinding movement of the drum when it is unclutched from the shaft when the elevator is to be lowered. Then the clutch is thrown in and the brake released the drum will be rotated and the elevator raised. When it is desired to lower the elevator the brake is set and the drum unclutched from the shaft and then by manipulating the brake the elevator can be gradually restored to its vertical position ready to receive another barrel. In order to reduce the strains on the hoisting drum mechanism and to prevent accident should the drum cable break or become disconnected, I provide a drum 4C8 extending crosswise of the machine for a chain or cable 49 whose front end extends over the sheave 50 and is secured to the elevator bail 24, a weight to being secured to the other end of the chain. A ratchet wheel 51 is secured to the drum and on a rod 52 is pivoted the pawl 53 for engaging with the ratchet wheel to prevent unwinding of the drum after any winding up movement thereof, the weight turning the drum 48 as the elevator rises. If anything should happen to the hoisting mechanism during raising of the elevator with the heavy barrel thereon, the ratchet drum arrangement will lock the elevator and prevent sudden falling thereof. In order to disconnect the ratchet drum mechanism to permit lowering of the elevator 1 provide tripping mechanism for the pawl 53. As shown, a rod 5a is pivoted in brackets 55 and has its inner end 56 deflected laterally into position below the pawl, the outer end 57 of the lever extending laterally in the opposite direction and connected with an actuating lever or cord 58, a pull on which will rotate the tripping lever to raise the pawl from the ratchet wheel.

Describing now the mechanism for removing the contents from a barrel B after it hasbcen elevated into horizontal position on the machine, shaft 59 is arranged on the machine in line with the barrel axis and carries at its front end a suitable tool T for cutting out the barrel contents. The rear end of the shaft is threaded and extends through the threaded bushings 60 and 61 supported in the bearing frames 62 and 63 mounted on the rigid cross bars 64 and 65 connecting the side frames of the machine. Between the bushings 60 and 61 a pulley 66 receives the shaft and has a key 67 for engaging in the key slot 68 cut in the threaded end of the shaft so that when the pulley is turned the shaft will be turned therewith in the threaded bushings 60 and 61 and the shaft will be shifted longitudinally forwardly to carry the tool T into and through the barrel. In front of its threaded section the shaft passes through the bearing frame 69 between collars 70 and 71 secured to the shaft, and this frame 69 is secured to a cross beam 72 which at its ends has guide tongues 73 and 74. extending through the guide slots 75 and 76 in the guide bars 77 and 78 secured to the framework sides 10 and 11. As the shaft turned the beam 72 travels forwardly and supports the shaft to keep the tool T alined in the barrel. construction for cutting, shaving, or loosening the barrel contents. Figs. and 6 show a simple construction. A sheet metal disk '79 is secured to the end of the screw shaft by means of brackets 80 and the disk has one or more radially extending slots 81 ad jacent one edge of which the disk material is deflected outwardly to form a blade 82 whose outer edge is sharpened. The disk will therefore operate like a bit to cut the barrel contents as the screw shaft is rotated, the shaved off slices or slabs passing forwardly through the slot 81 and out of the barrel. A trough 83 may be secured to the machine frame-work below the barrel mouth and constructed to discharge the material where desired.

Describing the driving mechanism for the screw shaft, a counter shaft 8a is j ournaled in bearing frames 85 and 86, forward and reverse pulleys 87 and 88 being pivoted on the shaft and connected by belts 89 and 90 with the pulleys 91 and 92 on the main drive shaft. The shaft 84 has secured thereto a transmission pulley 93 which is connected by belt 94 with the pulley 66 on the screw shaft.

The tool may be of any suitable Between the forward and reverse pulleys 87 and 88 suitable clutch mechanism is mounted for connecting either pulley with the shaft. As shown, a clutch head 95 is slidable on the shaft by means of a clutch lever 96 pivoted at its upper end to a bracket 97. By means of suitable clutching mechanism 98 the pulley 88 will be connected with the shaft 84: for

rotation and by means of clutching mechavided with a grip 104. When the cord is the clutch lever 96 when swung rearwardly.

to set the machine for forward drive of the tool, a spring 108 tending to hold the latch The latch lever has in latching position. the arm 109 through which extends the rear end of a trip rod 110. This rod extends through the guide bracket 111 mounted on the beam 72 and at its front end has the adjustable abutment 112. After pull on the cord 102 to swing the clutch lever 96 into the latch lever 106, the screw shaft will be rotated and the tool shifted forwardly into and through the barrel, the beam 7 2 traveling forwardly with the shaft. The front wall of the bracket 111 will reach the abutment 112 on the trip rod when the tool reaches the bottom of the barrel and then a slight forward shift of the trip rod will swing the latch lever 106 to release the clutch lever 96 and the spring 101 will throw the lever past neutral and into forward position to disconnect the forward driving mechanism and to connect in the reverse driving mechanism, the screw shaft being then shifted back toward normal position. As the beam 72 travels rearwardly with the screw shaft its detent plate 100 will encounter the clutch lever and will swing it rearwarclly until the lever assumes its normal neutral position, whereupon the driving stops and the screw shaft come to rest in neutral position. The reverse pulley 88 is preferably smaller than the forward pulley 87 in order that the shaft is restored to neutral position in a short time.

Brieflly summing up on the operation, a barrel is placed on the lowered platform and the clutch lever 45 pulled to clutch in a hoisting drum 28 whereupon the elevator is raised and tilted to bring the barrel with its axis in line with that of' the screw shaft 59. During raising of the elevator the weight w rotates the drum a8 andthe pawl locks the drum so as to prevent sudden dropping of the barrel. and elevator should the hoisting apparatus fail. The cord 102 is then pulled and the clutch lever 96 swung rearwardly from its neutral position to cause clutching of the pulley 87 to the shaft 84 and then upon driving of the pulley 66 the screw shaft 59 will be rotated and shifted longitudinally forwardly, the rotating tool T passing into the barrel and cutting out the contents. lVhen the clutch lever 96 is swung rearwardly it is received and held by the latch 106 and the screw shaft continues to rotate forwardly and to advance until the bracket 111 strikes the abutment nut 112 on the trip rod, the resulting rotation of the latch 106 releasing the clutch lever 96 which is thrown forwardly by the spring 101 through neutral position and into fore wand position to cause clutch 98 to become effective whereupon by means of the cross belt :90 and the small pulley 88 the .screw shaft will be shifted rearwardly to with draw the tool from the barrel. the abutment plate 100 on the traveling support 72 encounters the clutch lever 96 it carries it back into neutral position to release the clutch 98, whereupon the screw shaft stops with its tool .1 in normal position in front of the barrel. During withdrawing movement of the tool from the barrel any of the contents still remaining will be pulled out. To remove the empty barrel, the op erator steps on the treadle to raise the tongue 34 and to release the detentbar 29, and he also pulls on the cord 59 to release the counter weight drum 48 from the pawl 53. Then by operating the brake 47' on the hoisting drum, the elevator with the empty barrel can be-gradually dropped back to the floor and the empty barrel removed. The machine being on wheels, it can be readily moved about, and by a suitable chute 83 the discharged material can be guided to and discharged where desired.

I do not desire to be limited to the exact construction, arrangement and operation shown and described as modifications are no doubt possible which would still come within the scope of the invention.
